In two sulfide‐rich freshwater sediments from the Biesbosch and Kromme Rijn River in the Netherlands differing in carbonate content and acid volatile sulfide (AVS) content, metal and sulfide dissolution kinetics were studied at different acid concentrations by varying both the procedure of acid addition and the extraction time. The establishment of equilibrium was monitored by measuring the pH in time, which reached a near constant value. The equilibrium pH was reached quickly when large amounts of acid were added and slowly when small amounts of acid were added. This observation was confirmed by the yield of extracted metals after either a 45‐min or 24‐h extraction over a pH range from 0 to 5. The pH factor seemed to be of more influence than time for the dissolution of metals. The amount of extracted metals was highly dependent on the metal itself due to its physico–chemical behavior. Although the sediments studied varied in carbonate content, acid volatile sulfide (AVS), and total metal content, the extracted fraction of metals compared with their total content in the sediment was similar for most metals. Finally, the AVS content as well as the ratio of simultaneously extracted metals (SEM; sum of Cd, Cu, Ni, Pb, and Zn) to AVS decreased with increasing pH. Because the SEM to AVS ratio may be used to set environmental quality criteria for the sediment compartment, this observation is of significance. [ABSTRACT FROM AUTHOR]

Introduction: A minimum unit price (MUP) for alcohol of £0.50 per unit (1 UK unit = 10 mL/8 g alcohol) was introduced in Scotland in May 2018. Few previous studies have examined the impact of alcohol pricing policies on people who are alcohol dependent. This study aimed to evaluate the effect of MUP on people who are alcohol dependent including changes in alcohol consumption and health status, as well as potential unintended consequences., Methods: Three waves of cross-sectional data were collected in Scotland (intervention) and Northern England (control) at 0-6 months pre-implementation then 3-9 months and 18-22 months post-implementation. The sample was N = 706 people receiving treatment related to their alcohol use. We collected structured interview data including recent drinking information via a 7-day timeline-follow-back drinking diary. Difference-in-difference analyses estimated change in indicators in Scotland compared to England at both post-implementation timepoints., Results: The proportion of participants consuming alcohol costing on average <£0.50 per unit in Scotland decreased from 60.6% at 0-6 months prior to MUP implementation to 6.3% at 3-9 months post-implementation (p < 0.0004). There was no significant change in the indicators for alcohol consumption, severity of dependence, health status, other substance use, deprivation level or parenting., Discussion and Conclusions: The introduction of MUP in Scotland was associated with increases in the prices paid for alcohol by people with dependence and presenting to treatment services. There was no evidence of changes in their alcohol consumption or health status. There was also no evidence of harmful unintended consequences for this population., (© 2024 The Author(s).

Introduction: Scotland implemented a minimum price per unit of alcohol (MUP) of £0.50 in May 2018 (1 UK unit = 10 mL/8 g ethanol). Some stakeholders expressed concerns about the policy having potential negative consequences for people with alcohol dependence. This study aimed to investigate anticipated impacts of MUP on people presenting to alcohol treatment services in Scotland before policy implementation., Methods: Qualitative interviews were conducted with 21 people with alcohol dependence accessing alcohol treatment services in Scotland between November 2017 and April 2018. Interviews examined respondents' current and anticipated patterns of drinking and spending, effects on their personal life, and their views on potential policy impact. Interview data were thematically analysed using a constant comparison method., Results: Three key themes were identified: (i) strategies used to manage the cost of alcohol and anticipated responses to MUP; (ii) broader effects of MUP; and (iii) awareness and preparedness for MUP. Respondents expected to be impacted by MUP, particularly those on low incomes and those with more severe dependence symptoms. They anticipated using familiar strategies including borrowing and reprioritising spending to keep alcohol affordable. Some respondents anticipated negative consequences. Respondents were sceptical about the short-term benefits of MUP for current drinkers but felt it might prevent harm for future generations. Respondents had concerns about the capacity of treatment services to meet support needs., Discussion and Conclusions: People with alcohol dependence identified immediate concerns alongside potential long-term benefits of MUP before its introduction. They also had concerns over the preparedness of service providers., (© 2023 The Authors.

Issues: Numerous studies have explored alcohol consumption in pregnancy, but less is known about women's drinking in the early parenting period (EPP, 0-5 years after childbirth). We synthesise research related to three questions: (i) How are women's drinking patterns and trajectories associated with socio-demographic and domestic circumstances?; (ii) What theoretical approaches are used to explain changes in consumption?; (iii) What meanings have been given to mothers' drinking?, Approach: Three databases (Ovid-MEDLINE, Ovid-PsycINFO and CINAHL) were systematically searched. Citation tracking was conducted in Web of Science Citation Index and Google Scholar. Eligible papers explored mothers' alcohol consumption during the EPP, focusing on general population rather than clinical samples. Studies were critically appraised and their characteristics, methods and key findings extracted. Thematic narrative synthesis of findings was conducted., Key Findings: Fourteen quantitative and six qualitative studies were identified. The (sub)samples ranged from n = 77,137 to n = 21 women. Mothers' consumption levels were associated with older age, being White and employed, not being in a partnered relationship, higher education and income. Three theoretical approaches were employed to explain these consumption differences: social role, role deprivation, social practice theories. By drinking alcohol, mothers expressed numerous aspects of their identity (e.g., autonomous women and responsible mothers)., Implications and Conclusion: Alcohol-related interventions and policies should consider demographic and cultural transformations of motherhood (e.g., delayed motherhood, changes in family structures). Mothers' drinking should be contextualised carefully in relation to socio-economic circumstances and gender inequalities in unpaid labour. The focus on peer-reviewed academic papers in English language may limit the evidence., (© 2023 The Authors.

Aims: Evidence exists on the potential impact of national level minimum unit price (MUP) policies for alcohol. This study investigated the potential effectiveness of implementing MUP at regional and local levels compared with national implementation., Design: Evidence synthesis and computer modelling using the Sheffield Alcohol Policy Model (Local Authority version 4.0; SAPMLA)., Setting: Results are produced for 23 Upper Tier Local Authorities (UTLAs) in North West England, 12 UTLAs in North East England, 15 UTLAs in Yorkshire and Humber, the nine English Government Office regions and England as a whole., Cases: Health Survey for England (HSE) data 2011-13 (n = 24 685)., Measurements: Alcohol consumption, consumer spending, retailers' revenues, hospitalizations, National Health Service costs, crimes and alcohol-attributable deaths and health inequalities., Findings: Implementing a local £0.50 MUP for alcohol in northern English regions is estimated to result in larger percentage reductions in harms than the national average. The reductions for England, North West, North East and Yorkshire and Humber regions, respectively, in annual alcohol-attributable deaths are 1024 (-10.4%), 205 (-11.4%), 121 (-17.4%) and 159 (-16.9%); for hospitalizations are 29 943 (-4.6%), 5956 (-5.5%), 3255 (-7.9%) and 4610 (-6.9%); and for crimes are 54 229 (-2.4%), 8528 (-2.5%), 4380 (-3.5%) and 8220 (-3.2%). Results vary among local authorities; for example, annual alcohol-attributable deaths estimated to change by between -8.0 and -24.8% throughout the 50 UTLAs examined., Conclusions: A minimum unit price local policy for alcohol is likely to be more effective in those regions, such as the three northern regions of England, which have higher levels of alcohol consumption and higher rates of alcohol harm than for the national average. In such regions, the minimum unit price policy would achieve larger reductions in alcohol consumption, alcohol-attributable mortality, hospitalization rates, NHS costs, crime rates and health inequalities., (© 2022 The Authors.

Introduction: The UK low-risk drinking guidelines were revised in 2016. Drinkers were primarily informed about the guidelines via news media, but little is known about this coverage. This study investigated the scale and content of print and online textual news media coverage of drinking guidelines in England from February 2014 to October 2017., Methods: We searched the Nexis database and two leading broadcasters' websites (BBC and Sky) for articles mentioning the guidelines. We randomly selected 500 articles to code for reporting date, accuracy, tone, context and purpose of mentioning the guidelines, and among these, thematically analysed 200 randomly selected articles., Results: Articles mentioned the guidelines regularly. Reporting peaked when the guidelines revision was announced (7.4% of articles). The most common type of mention was within health- or alcohol-related articles and neutral in tone (70.8%). The second most common was in articles discussing the guidelines' strengths and weaknesses, which were typically negative (14.8%). Critics discredited the guidelines' scientific basis by highlighting conflicting evidence and arguing that guideline developers acted politically. They also questioned the ethics of limiting personal autonomy to improve public health. Criticisms were partially facilitated by announcing the guidelines alongside a 'no safe level of drinking' message, and wider discourse misrepresenting the guidelines as rules, and highlighting apparent inconsistencies with standalone scientific papers and international guidelines., Discussion and Conclusions: News media generally covered drinking guidelines in a neutral and accurate manner, but in-depth coverage was often negative and sought to discredit the guidelines using scientific and ethical arguments., (© 2022 The Authors.

Introduction: The positive impact of substance use treatment is well-evidenced but there has been substantial disinvestment from publicly funded treatment services in England since 2013/2014. This paper examines whether this disinvestment from adult alcohol and drug treatment provision was associated with changes in treatment and health outcomes, including: treatment access, successful completions from treatment, alcohol-specific hospital admissions, alcohol-specific mortality and drug-related deaths., Methods: Annual administrative data from 2013/2014 to 2018/2019 was matched at local government level and multi-level time series analysis using linear mixed-effect modelling conducted for 151 upper-tier local authorities in England., Results: Between 2013/2014 and 2018/2019, £212.2 million was disinvested from alcohol and drug treatment services, representing a 27% decrease. Concurrently, 11% fewer people accessed, and 21% fewer successfully completed, treatment. On average, controlling for other potential explanatory factors, a £10 000 disinvestment from alcohol and drug treatment services was associated with reductions in all treatment outcomes, including 0.3 fewer adults in treatment (95% confidence interval 0.16-0.45) and 0.21 fewer adults successfully completing treatment (95% % confidence interval 0.12-0.29). A £10 000 disinvestment from alcohol treatment was not significantly associated with changes in alcohol-specific hospital admissions or mortality, nor was disinvestment from drug treatment associated with the rate of drug-related deaths., Discussion and Conclusions: Local authority spending cuts to alcohol and drug treatment services in England were associated with fewer people accessing and successfully completing alcohol and drug treatment but were not associated with changes in related hospital admissions and deaths., (© 2021 The Authors.

Introduction and Aims: Alcohol Intoxication Management Services (AIMS) provide basic care for intoxication and minor injuries, have been increasingly implemented in urban areas characterised by a large number of premises licensed for the sale and on-site consumption of alcohol, with the goal of reducing alcohol's burden on emergency services, including referrals into hospital emergency departments. The acceptability of new health services to users is a key effectiveness outcome. The aim was to describe patient experiences when attending an AIMS and document the acceptability of AIMS to users., Design and Methods: A sequential mixed methods study was undertaken involving semi-structured interviews with participants from four AIMS followed by a survey of users recruited from six AIMS., Results: Interviewees (N = 19) were positive about the care they received in AIMS and appreciated the friendly, non-judgemental atmosphere. Survey respondents rated their experience in AIMS positively (on a 0 to 10 Likert scale, mean = 9.34, SD = 1.38, n = 188). Frequently given reasons for attendance included drinking alcohol (57%) and minor injury (42%); 24% said they would have attended the emergency department had the AIMS not been available and 6% said they would have preferred to go to the emergency department; 31% indicated they would have felt unsafe without the AIMS., Discussion and Conclusions: AIMS are acceptable to users. AIMS are likely to address previously unmet demand for a safe space within the night-time environment., (© 2019 The Authors.

Most high-income nations issue guidelines on low-risk drinking to inform individuals' decisions about alcohol consumption. However, leading scientists have criticized the processes for setting the consumption thresholds within these guidelines for a lack of objectivity and transparency. This paper examines how guideline developers should respond to such criticisms and focuses particularly on the balance between epidemiological evidence, expert judgement and pragmatic considerations. Although concerned primarily with alcohol, our discussion is also relevant to those developing guidelines for other health-related behaviours. We make eight recommendations across three areas. First, recommendations on the use of epidemiological evidence: (1) guideline developers should assess whether the available epidemiological evidence is communicated most appropriately as population-level messages (e.g. suggesting reduced drinking benefits populations rather than individuals); (2) research funders should prioritize commissioning studies on the acceptability of different alcohol-related risks (e.g. mortality, morbidity, harms to others) to the public and other stakeholders; and (3) guideline developers should request and consider statistical analyses of epidemiological uncertainty. Secondly, recommendations to improve objectivity and transparency when translating epidemiological evidence into guidelines: (4) guideline developers should specify and publish their analytical framework to promote clear, consistent and coherent judgements; and (5) guideline developers' decision-making should be supported by numerical and visual techniques which also increase the transparency of judgements to stakeholders. Thirdly, recommendations relating to the diverse use of guidelines: (6) guideline developers and their commissioners should give meaningful attention to how guidelines are used in settings such as advocacy, health promotion, clinical practice and wider health debates, as well as in risk communication; (7) guideline developers should make evidence-based judgements that balance epidemiological and pragmatic concerns to maximize the communicability, credibility and general effectiveness of guidelines; and (8) as with scientific judgements, pragmatic judgements should be reported transparently., (© 2018 Society for the Study of Addiction.)

Aims: To compare the proportion of people in England with probable alcohol dependence [Alcohol Use Disorders Identification Test (AUDIT) score ≥ 20] with those with other drinking patterns (categorized by AUDIT scores) in terms of motivation to reduce drinking and use of alcohol support resources., Design: A combination of random probability and simple quota sampling to conduct monthly cross-sectional household computer-assisted interviews between March 2014 and August 2017., Setting: The general population in all nine regions of England., Participants: Participants in the Alcohol Toolkit Study (ATS), a monthly household survey of alcohol consumption among people aged 16 years and over in England (n = 69 826). The mean age was 47 years [standard deviation (SD) = 18.78; 95% confidence interval (CI) = 46.8-47] and 51% (n = 35 560) were female., Measurements: χ 2 tests were used to investigate associations with demographic variables, motivation to quit drinking, attempts to quit drinking, general practitioner (GP) engagement and types of support accessed in the last 12 months across AUDIT risk zones., Findings: A total of 0.6% were classified as people with probable alcohol dependence (95% CI = 0.5-0.7). Motivation to quit (χ 2  = 1692.27, P < 0.001), current attempts (χ 2  = 473.94, P < 0.001) and past-year attempts (χ 2  = 593.67, P < 0.001) differed by AUDIT risk zone. People with probable dependence were more likely than other ATS participants to have a past-year attempt to cut down or quit (51.8%) and have received a specialist referral from their GP about drinking (13.7%), and less likely to report no motivation to reduce their drinking (26.2%). Those with probable dependence had higher use of self-help books and mobile applications (apps) than other ATS participants; however, 27.7% did not access any resources during their most recent attempt to cut down., Conclusions: Adults in England with probable alcohol dependence, measured through the Alcohol Use Disorders Identification Test, demonstrate higher motivation to quit drinking and greater use of both specialist treatment and self-driven support compared with those in other Alcohol Use Disorders Identification Test zones, but most do not access treatment resources to support their attempts., (© 2018 Society for the Study of Addiction.)

Introduction: Environmental and societal factors are significant determinants of children's initiation to and use of alcohol. Schools are important settings for promoting well-being and substantial resources have been devoted to curriculum-based alcohol programs, but the effects of these in reducing the misuse of alcohol have been modest. Adults can and do consume alcohol at school events when students are present, but there is a dearth of evidence about parents' level of support for the practice. The aim of this study was to examine parents' level of support for the purchase and consumption of alcohol at primary school fundraising events when children are present., Methods: Four hundred seventy-nine Australian parents of children aged 0-12 years participated in an online survey. Logistic regression was used to assess the impact of parent characteristics on the level of agreement with parental purchase and consumption of alcohol at school fundraising events when children are present., Results: The majority of parents (60%) disagreed/strongly disagreed with the practice of adults being able to purchase and consume alcohol at school fundraising events when children were present. The 21% of parents who supported the practice were more likely to be daily smokers and/or have higher (>6) Alcohol Use Disorders Identification Test-alcohol consumption scores., Conclusions: Despite the fact that the majority of parents disagree with this practice, published reports suggest that adults' use of alcohol at primary school events is an emerging issue. It is important that school decision-makers are mindful of the financial and educational value of fundraising activities., (© 2014 Australasian Professional Society on Alcohol and other Drugs.)
